UND will be looking for a new offensive line coach.
Rod Carey took a similar position at Northern Illinois on Wednesday.
"It's a good move for Rod," Sioux coach Chris Mussman said. "I'm happy for him."
Northern Illinois beat UND 23-17 in September in DeKalb. After the season, former NIU coach Jerry Kill left for Minnesota, taking a handful of assistants with him.
The search for a new O-line coach at UND will begin sometime after the recruiting season ends.
